Can yum avoid major upgrade but still apply necessary security fix?

  • 772

For example, if the server (CentOS) has PHP 5.2.6 installed and has added a third party repository that provides both PHP 5.2.12 and PHP 5.3.1.

PHP 5.2.12 and PHP 5.3.1 are the latest versions for PHP 5.2 and PHP 5.3 respectively.

When yum update command runs, will yum simply upgrade PHP 5.2.6 to PHP 5.3.1?

Or it has some intelligence that a major upgrade (5.2 to 5.3) may cause problems and thus to be safe, it decides to upgrade to PHP 5.2.12 instead?

By the way, will a repository contain multiple versions of a package, or it only contains the latest version?

linux yum rpm update

    If you are using the remi repos there's a lot of help here - I used this upgrading Fedora 6:

    yum --enable remi --exclude=mysql-libs install php

    Although more generally, all you need is

    yum upgrade php

    Or for a specific version, remove .i386 etc, add a hyphen then add the version

    yum install php-5.3.1-1.fc6.remi

    Alternatively

    yum check-update

    Will show you all packages and

    yum update --exclude=kernel

    Will update everything except kernel packages etc

    By the way, will a repository contain multiple versions of a package, or it only contains the latest version?

    Generally the maintainer will only provide the latest version, however it's possible to have more than one version in a repository.
